regulator: tps6586x: Prepare supporting fixed regulators
Add the required definitions and macros to allow easily adding fixed regulators. This required for the TPS658640 that doesn't allow setting the LDO_RTC output voltage. Signed-off-by: Alban Bedel <alban.bedel@avionic-design.de> Signed-off-by: Mark Brown <broonie@linaro.org>
